Glad to be here…Eric’s the man…Ok my CEL is on so I scanned it with my OBDII Scanner…It read 2 codes…P0456 and P0456 (Pending)…I’ve changed the Gas cap,Evap Canister,Evap Hose that connects to the Canister and the Purge Solenoid Valve twice. So what should I do next short of taking it to a stealership?

Stop replacing parts for starters. With evap leaks especially small ones you really need to follow the factory service procedure which usually requires hooking up a smoke machine and activating the different components and valves in the system to verifiy their operation, it’s not something you can ‘short cut’ really or throw parts at. I’m hoping one of the forum members has a service procedure for you and your vehicle. BTW according to your code the leak is on the canister side so replaicng the gas cap or anything on that side of the system is a waste of time. Come to think of it since one of those codes is pending you might just want to clear them and see if they come back, you might have fixed it already, it takes some time for the computer to run the test for the leak again as a certain set of conditions needs to be met before it will run the test to clear the code.
Hi mopar426,
I would recommend having the EVAP system smoked for leaks. Usually an independent shop (and definitely a dealership) will have the proper equipment to diagnosis this problem creating the CEL P0456. It is well worth it to have this performed. Otherwise, as you can probably attest to, it can be frustrating with swapping out parts in hopes of a fix. Good luck and keep us posted.
